Cha Du-ri of FC Seoul played the whole match against Australia’s Central Coast in the group stage of the Asian Champions League on Tuesday, contributing to his team's 2-0 win at home.
However, he felt pain in his left leg during the game and a medical examination showed that 10 percent of his hamstring had been damaged. The injury effectively rules him out of the national team's upcoming matches.
The Korean squad will be called up this Saturday for training ahead of a tune-up against Greece next Thursday.
Manager Hong Myung-bo plans to select a player to replace Cha, who was included in the roster for next week's game.
